Tohline将研究气体云的坍缩形成 恒星，使用超级计算机和广泛的成像， 计算气体云。 他也会开始计算崩溃 从一系列新发现的数学解决方案， 旋转云或从一组解决方案的大规模吸积 磁盘。 他将追踪不稳定性的发展， 尤其是那些导致裂变成更小碎片的物质。 已知恒星是由小而致密的 星际云 众所周知，云的旋转 重要的是，部分原因是大多数恒星都是成对出现的。 但 旋转云的实际崩溃尚未被追踪。 将 云裂成了碎片 产生的恒星 旋转？ Tohline将使用一台超级计算机来调查这些 问题，并将使用计算云的图像来确定 哪些解决方案最接近自然界中的解决方案。

Tohline will investigate the collapse of gas clouds to form stars, using a supercomputer and extensive imaging of the computed gas clouds. He will start the computed collapse either from a series of newly discovered mathematical solutions for rotating clouds or from a set of solutions for massive accretion disks. He will trace the development of instabilities, especially those that cause fission into smaller pieces. Stars are known to form by the collapse of small, dense interstellar clouds. Rotation of the clouds is known to be important, in part because most stars occur in binary pairs. But the actual collapse of rotating clouds has not been traced. Will the cloud split into pieces? How fast will the resulting stars rotate? Tohline will use a supercomputer to investigate these questions and will use images of the computed clouds to determine which solutions most resemble those in nature.
